Because that is stupid, you have been told this before.

@@wnytrashtrucks I just want to know.

It wouldn't make sense to use side loaders in this part of the city because it's mostly apartments and multifamily buildings. The population density means more parked vehicles so there wouldn't be much room to line up multiple barrels, per building. An automated side loader wouldn't be efficient in areas like these because the driver would still have to continuously exit the truck to bring barrels to the truck and return them to wherever they were.

@@94tristen_thetrashman Thank you. ❤️

@LuisUrbieta. - In the UK and Europe they are. All they do is 'hook' the bin on - it goes up automatically (No levers or buttons to push), gets emptied, and comes back down - (Undamaged), - and they don't fall in the cart either.
